Capacitor life

I think that those are hand made capacitors, so life span is questionable.

Replace them with capacitors made by a major industrial capacitor manufacture.

Are you sure that REL-CAPS PPT caps are electrolytic? It would seem strange to me be fit a high quality speaker with cross overs that might fail after only 20 years.

I think that they are film rather than electrolytic capacitors.

But they are hand made. That alone makes them suspect.

Well I believe ‘REL’ in the name is short for reliable, and so I’m not particularly convinced by that argument.

I think that you are correct!

It was Handmade Electronics Co. that was selling them.

in which case Reliable brand capacitors should last a century.

PPT is a polystyrene film cap. It is a very high quality type and should last a very long time. Why does “hand made” make a difference?

It takes very big, very expensive machines to make good capacitors, the exact opposite of "hand made" capacitors.
